I only know one Samurai movie. Seven Samurai.

Check out Kurosawa's other movies, like Yojimbo. Also look for the Lone Wolf and Cub/Baby Cart series, the two Lady Snowblood movies, and the original Zatoichi movies. That ought to keep you busy for a bit.

Zatoichi or Ghost Dog.

7 Samurai

My personal favorite is "The Sword Of Doom" - http://www.imdb.com/title/tt0060277/

The only one I've seen was "After the Rain" (雨あがる), for which Akira Kurosawa worked on the screenplay. I don't watch very many samurai movies at all, but I really, really enjoyed this one. I highly recommend it.

Rashomon is the best Kurosawa samurai movie in my book.

Izo if you like Miike.

The Last Samuri was a pretty good movie.

Unfortunately I can't post links because of so much script down-voting. Check it out on google.

Scr3w the samurai. Watch Shaolin vs Ninja :D And all the other great karate movies from the 80s. So much fun especially the ones with Jackie Chan

"Throne of Blood" is very good, retelling of Macbeth in feudal Japan so instead of knight's and kings, samurai and shogun. The plot of the original play fits and works in the time period perfectly with minimal changes.

Harakiri / Seppuku (1962) is a totally gut-wrenching experience.

13 Assassins is amazing if you haven't seen it. it starts off almost painfully slow, but the payoff is worth it.

Definitely check out Masaki Kobayashi's Harakiri. As much as I love Kurosawa's work (He's my favourite director and I've seen all his films on 35mm), Harakiri is one step ahead. Not only is it a great samurai movie, it is also a poignant critique of Japanese society and the samurai code of honor. It's an anti-samurai samurai movie, if you will. At its core is a tremendous performance by Tatsuya Nakadai. I'm always amazed when I see him in this role of the aging samurai: He was 28 at the time this film was shot, yet he brings a world-weariness and sadness to it. At the same time there is such dignity in the character. Nakadai is an amazing actor and I've never seen him be anything but pitch-perfect in anything that he's been in - but this one has to be his best performance. I love the soundtrack by Toru Takemitsu. It's entirely played on traditional Japanese instruments and heavily influenced by Noh-Theater. But, my god is it good! The biwa is played with a harshness that makes it sound like an electric guitar.

Ran by Akira Kurosawa is mesmerizing. The most beautiful movie i have ever seen. This is perfection and any filmmaker worth his salt will shed tears while watching this film, because they will never be able to create anything matching Ran's level of perfection.

There are so many other great Samurai movies out there, a lot of them have already been named (like The Sword Of Doom - another amazing performance by Nakadai and one of the most ferocious endings in film history - or Kurosawa's other works). The two I mentioned above are essential viewing. Otherwise, just go ahead and explore!

Ran, which is Kurosawa's last epic.

As a piece of trivia, it held the honor of being the most expensive Japanese film ever produced up to that time.
